CLYDE J. COLEMAN, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO ALBERT F. .WINEMAN, OF SAME PLACE.

CONNECTOR FOR ELECTRIC WIRES.

. SEEMI IGATION forming part of Letters Patent No. 468,293, dated February 2, 1892.

Application filed June 15, 1891.

To all whdm it may concern: Y

Be it known that I, CLYDE J. COLEMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improved Connector fOPElGBlZI'lC Conductors; and I do hereby declare the following to boa full, clear, and exact description of the same,

, reference being had -to the accompanying drawings, forming a part of this specification. This invention relates to that class of con-" nectors for elctric'wires or conductors in which a tubular sleeve is employed to receive the conductor ends, a joint being formed by compressing or reducing the sleeve upon the conductor ends. a v i The object of the present improvement is to provide a simple and effective couplingsleeve for such purpose-embodying the features of 'cheapness of manufacture, ease and convenience in application, combined with great strength and holding capacity in the joint, as well as perfect electric contact or conneetion between the conductor ends. I attain such object by the construction and arrangement of parts illustrated in the accompanying drawings, in which l Figure 1 is a perspective view of couplingsleeve; Fig. 2, a longitudinal section of the joint as formed between electric conductors of an even diameter; Fig. 3, aperspective view showing the application of the coupli ng-sleeve in attaching a'branch Wire to the main eonductor; Fig. 4:, a similar View showing the ape plication of the samerto a main conductor and two branches. Similar numeralsof reference indicate like parts in the dilferent views.

Referring to the drawings, 1 represents the coupling sleeve or socket of an open-sided 25th vday-ofjApril, 1891.

Serial No. 396,864- (No model.)

Manama... longitudinal slit 2 extending the entire length of the same. The inner periphery of the sleeve is formed into a series of circularly-arranged and inwardly-projecting teeth 3, either by the usual milling or pressing methods thatare adapted when the coupling-sleeve is compressed uponthe adjacent ends of electric wires or conductors 4 to embed themselves into the surface of the wire, l

as illustrated in Fig. 2, to form not only a very strong and effective mechanical connection of the parts, but a nectiouas well. a a

My improved coupling-sleeve is equally adapted for coupling or joiningthe ends of wires of an equal or unequal diameter, as well as for attaching branchwires, as fully illusvery perfect electric contraced in the drawings, and it is within the scope of my present invention to so use and apply-the same in practical use to meet the varied circumstances and requirements of such use.

Having thus fullydescriloed my said inven-' tion,what I claim as new, and desire to secure by Letters Patent, is-- A coupling or connector for electric wires or conductors, comprising an open-sided sleeve having on its inner periphery a series of circularly-arranged inwardlyprojecting teeth that are adapted when the sleeve is compressed to embed themselves into the surface of the wire ends and form both a strong mechanical and perfect electrical connection, es.- sentially as herein set forth.

In testimony whereof witness my hand this a CLYDE J. COLEMAN. In presence of- ROBERT BURNS, A. F; WINEMAN.
